Studies on certain activities of Egyptian honeybees (lamarckii cockerel) in Siwa Oasis [electronic resource].

Includes references.

Study results indicated that Egyptian honeybee activities fluctuated under Siwa weather condilions. Two peaks of worker and drone brood were recorded. The first and minor one occurred at April. Monthi~ mean areas measured were (205.13 & 198.12 inch² / col.) and (11.78 & 25.17 inch! colony). while the major peak was in June. Sealed brood areas were (240.15 & 213.15 inch² / col.) and (80.35 & 75.12 inch² / col.) in the two years of the study respectively. A significant positive correlation was found between rearing workers, drones and temperature degrees. The lowest brood rearing was noticed during Aug.. Sept., and Oct. In spite of markedly decrease in temperature degree in Nov.. brood rearing activities increased due to the availabie pollen gathered from Eucalyptus. Pollen gathering activity has also two peaks, the first was recorded at Apr., while the second was at June. Mean of stored pollen areas in those peaks were (38.12 & 50.87 inch² / col.) and (86.66 & 93.15 inch² / col.) in the two years respectively. A positive correlation have found between pollen gathering and brood rearing activities. but relative humidity had a close negative effect. Maximum number of constructed queen cells were (33.16 & 43.16), in June during the two years. The maximum measured areas of stored honey were (211.53 & 230.70 inch² / col.) in the end of June during the investigated years respectively. Accordingly Siwa Oasis seems to be more profitable for rearing and propagating Apis mel/ifera lamarckii.
